Can you get there? I would hope so, with proper training, but maybe not by the time of your first race. I'm no expert but here is what I would suggest. Running short intervals should help - 200s, 400s, 800s. Do them once a week instead of one of your regular runs, not adding a day. Do a good warmup of a mile or so easy before and the same after. Pick a specific time, like 75 secs and try to hit that on each. Recovery of 60 secs should be OK, walking or jogging. You may not be able to do 9 to start. When you start to have trouble hitting your time, it's time to go home. But you should be able to increase the number each week. An alternative to adding more repeats is to bring down the time, maybe 72 secs instead of 75.
